Brass is widely used as turbine material for cooling system for marine propellers. However, it is vulnerable to corrosion by contact of air or aqueous chloride solution. The essential oil of Myrtus communis (MO) was tested as a brass corrosion inhibitor (Cu70-Zn30) immersed in the 3% NaCl solution, using a polarization technique and electrochemical impedance spectroscopy. The effect of MO concentration, temperature and immersion time was studied to evaluate the action of the inhibitor. The results showed that the protection efficiency was enhanced with the increasing of MO concentration, and the potentiodynamic polarization experiment showed that MO acts essentially as a cathodic inhibitor. In addition, experiments have shown that MO inhibition efficiency decreases with increasing immersion time and temperature. The film adsorbed on the brass surface containing MO was confirmed by the results of the Scanning Electron Microscope (SEM) and the Energy Dispersive X-ray (EDX). The overall results affirmed the potential use of MO as inhibitor agent of brass corrosion in the 3% NaCl solution.

“…14,25 The tabulated data indicate that the corrosion current density (i corr ) decreases with increasing CA leaf extract and Linalool concentrations while the percentage of inhibition efficiency (h) increases. The h values show that, at any given concentration, CA leaf extract is more efficient than its active chemical ingredient Linalool.…”

Bitter orange, Citrus Aurantium (CA), extract and one of its chemical constituents, Linalool, have been evaluated as a corrosion inhibitor for mild steel in 0.5 mol L -1 hydrochloric acid (HCl) solution using potentiodynamic polarization, electrochemical impedance, Fourier transform infrared spectroscopy (FTIR), and atomic force spectroscopy (AFM) techniques. Functional groups of CA and Linalool were identified by FTIR spectroscopy. The Potentiodynamic polarization and electrochemical impedance studies showed that CA and Linalool act as mixed type inhibitors. The activation parameters showed that the corrosion inhibition takes place by spontaneous physical adsorption on the mild steel surface. Thermodynamic-kinetic model and Flory-Huggins isotherms were used to investigate the adsorption characteristics of CA and Linalool. The surface morphologies of mild steel specimens were studied using AFM, in which the surface roughness of the metal specimens on a micro scale was characterized.

The inhibition effect of grieseofulvin against the mild steel corrosion in 1 M HCl solution has been investigated by potentiodynamic polarization measurements, electrochemical impedance spectroscopy (EIS) and quantum chemical methods. It was found thatgrieseofulvin acts as a good mild steel corrosion inhibitor in the acid solution at temperature ranging from 298-328 K. The potentiodynamic polarization study reveals that grieseofulvin acts as mixed type inhibitor. The adsorption of grieseofulvin on mild steel follows the Langmuir adsorption isotherm. Scanning electron microscopy equipped with energy dispersive spectroscopy (SEM-EDS) studies established that grieseofulvin formed a protective layer on the surface of mild steel. * Corresponding Authors
